Detailed Description

Calculates and write the shear-stress at wall patches as the volVectorField field 'wallShearStress'.

\[ Stress = R \dot n \]

where

$ R $ = stress tensor
$ n $ = patch normal vector (into the domain)

The shear-stress symmetric tensor field is retrieved from the turbulence model. All wall patches are included by default; to restrict the calculation to certain patches, use the optional 'patches' entry.

Example of function object specification:

    wallShearStress1
    {
        type        wallShearStress;
        libs        ("libfieldFunctionObjects.so");
        ...
        patches     (".*Wall");
    }
Usage
Property Description Required Default value
type type name: wallShearStress yes
patches list of patches to process no all wall patches
Note
Writing field 'wallShearStress' is done by default, but it can be overridden by defining an empty objects list. For details see writeLocalObjects.
